Sonic 3 & Knuckles: Master Edition 2 Extra Mode is a ROM hack of the classic Sega Genesis game Sonic 3 & Knuckles. It expands upon the original game by adding new levels, zones, and gameplay mechanics. The original Sonic 3 & Knuckles was developed by Sega Technical Institute and released in 1994, known for its innovative level design and the introduction of Knuckles the Echidna as a playable character.  Gameplay in this ROM hack retains the core elements of the original game: fast-paced platforming, exploration of expansive levels, and the use of Sonic's signature spin dash. However, the 'Master Edition 2 Extra Mode' significantly increases the challenge and adds content not found in the original release.  The creators of this ROM hack are likely independent developers within the ROM hacking community, building upon the foundation of Sega's iconic game.
